Another Orange tractor? Can you identify?

This tractor was my great grandpas, I just found the picture as I am going through lots of old belongings. Can any one ID it?
1920s or 30s Case

For you gun guys, if you look real close the exhaust has been Magna-ported.

Thanks
Rick

Cross motor Case and should be gray.

It's a Case Cross Motor I would say.

That tall tube looks like the intake to the engine instead of the exhaust.

I'm not a Case guy though!

My neighbor had a bigger one and called it the L cross motor.

Definitely not an L, as that model had the engine mounted in-line. As this is a cross-motor tractor, it is 1929 or earlier.

Looks like a Case 9-18, type b, I think.

I'm not familliar with the cross motors, but you can go to the case board and ask there, they will know for sure.

not orange, thought those were gray

The tractor is a Case 9-18 or a 10-18. Both models were painted green.

As early as 1910, there was a growing demand for small, lightweight tractors. Most companies were still producing large, heavyweight machines, as it was believed only such tractors would adequately compete with steam engines. Few people believed that a machine could replace the horse or mule as a power source. Against this backdrop, and a growing volume of books and articles on power farming, Case introduced the 9-18 tractor in 1916. It was a four cylinder vertical crossmount engine set in a steel frame. It had a 3.7/8 by 5 inch bore and stroke, operating at 900 RPM. The crossmount design made it easy to power the rear wheels by a gear drive. The tractor was completely enclosed, giving a clean, sculptured look with a sloping hood design. Both the 9-18 and 10-18 were painted green. The 9-18 was built only from 1916 to 1918, with total production of about 6,000 units. It is also of interest to note that a number of these tractors were exported to Europe and South America. The 9-18 was phased out in 1918 and replaced by the 10-18. The increased horsepower was obtained by speeding the engine 150 RPM to 1050 RPM. Basically, the 10-18 was similar except for minor improvements such as a cast frame, which would be used on future models. The tractors operated on kerosene, but were started on gasoline. The manifold was designed to pre-heat the fuel before drawn into the engine. Case pioneered a centrifugal air cleaner, and an air washer attached to the side of the engine. Under very dusty conditions, the dirt and water was to be changed once or more daily. Since the tractors operated only on steel wheels, the dust was a major detriment to all operating parts of the power train and engine. The 10-18 could pull a two-bottom plow and power a small thresher. Since the belt pulley operated directly from the crankshaft, there was a minimum loss of belt horsepower. The 10-18 was manufactured from 1918 to 1922. It is estimated about 9,000 tractors were manufactured. These two tractor models were the Case Company's entries to the small tractor market.

@ Rick Kr:

In the book "Antique American Tractor And Crawler Value Guide" by: Terry Dean & Larry L. Swenson - on page 37, they have a picture (black & white) of a Case 9-18, and it is very similar to the tractor in your photo. The only differences that I can see are the wheels on the one in the book are without cleats; and the air-cleaner is different. I would have to agree with Lyn Jones that yours is either a 9-18 or a 10-18.

Very nice restoration, and a very detailed comentary on the little Case cross motor.

Now folks this is what this Discussion Board is all about.

Green is correct for this model, either a 9-18B or a 10-18.

Thanks to all of you. Now when it warms up a little I am going to walk all the fence rows and see if there is any sign of it parked out there somewhere.

I have been on the farm where the picture was taken in 30 years. But no too much has changed. Maybe this summer I will have another picture of it.

Thanks again,
Rick

Oops, meant to say I have not been on that farm in 30+ years.
